PARQUET-FLOOR.

SPECIFICATION forming part of Letters Patent No. 256,306, dated April11, 1882.

Application tiled December 9,1881. (No model.) Y

To all whom 'it may concern: Y l

Be it known that I, ROBERT WILH. ELTZ- NER, ot' the city, county, `andState of New York, haveinvent-ed 'certain new and useful Imof metalliccleats, which are driven into the adjoining edges of the blocks in suchamanner that a rigid connection of the blocks Within each exteriorfastening-band is obtained and provenients in ManufacturingPar'quet-Floors,.-that they are tirml y unitedv without the use of ofwhich the following is a specification.

This invention relates toan improved method of manufacturingparquet-doors from wood without the use of glue or Lother bindingmaterial; and the invention 'consists of a number of properly-selectedpieces of wood of different colors and suitable length, which are unitedtogether by exterior metallic bands' and transverse fastening strips orrailsafhso that when the pieces have been so connected they can beseparated, by transversely sawing through them,into as many panels asbannds have been used. The panels may be used for doors of rooms as wellas for ogripgwolialls and pavements of passage-ways.

In the accompanying drawings, Figures 1,2, and 3 represent side views ofdifferent blocks from which thejijningglus for parquet-floors areobtained, the dotted lines represen ting the lines of sawing off thepanels. Figs. 4t, 5, and 6 are plan views of dierent panels. Figs. 7, 8,and 9 are side views ofthe individual panels shown in Figs. L, iaudFigs. l0, 1l, and 12 show Y the applicati'mii the same principle tostone.

Similar letters ot' reference indicaievcorresponding parts.

According to the design in which the par quet-loor is desired tobe laid,there are formed anumber of blocks of square cross-section fromlongitudinal pieces o ot' wood of square crosssectmiitable length, whichpieces differ in eolor according to the design. AThese longitudinalpieces of wood a are laid up together to form a composite log and unitedeX- teriorly by means t' metallic bands b, which are fastened parallelto each other around the composite log formed 'bythejpieces u atintervals of equal or varying width, according to the style of'parquet-flooring to be produced.

Between the individual blocks or pieces a of the composite log areinterposed in the plane ot' each exterior bandfb, and of the same widththerewith, transverse metallic strips 1@which are nailed to the blocks,as shown clearly in Figui. The blocks or pieces c may also be connectedtransversely with each other by means are tilled up afterward bysuitable material.

more exactly the strips have' been fitted into v the wood.

The thickness of the exterior bands,b, should be only one/halt' ofJ thethickness ot' the trans verse strips, sol as to obtain throughout theparquet-floor a unifpripwjdth of joint.

It" desired, the parquet-floor can be made perfectly waterland re proofbyimpregnating the wood with pilqper cheinjcals. The panels can beplaced upoiwfo'undations of `wood, cement, asphaltum, or other suitablematerial.

It is obvious that by a proper arrangement ot' colors a number ofdesigns can be obtained, so that a very ornamental, durable, and cheapparquet-door is the result. a

, The same principle may also be applied to stone, only with thisdifference, that instead of exterior connecting-bands, galvanizedmetalframes have to be used, to which the crossstrips are rigidlysecured. Inthis case the open joints will be preferred, so as to give a betterfoothold. The panels are cut oft'vby a stone-sawing IOO I am aware thatwood tiles have been obtained by being transversely sewed oi fromcomposite logs the blocks or pieces of which have been glued together. Iam also aware 5 that parquet-homing hns been made of sections which areconnected to each other by mea-ns of tongues or grooves. To thesefeatures I lay no claim, ns I desire to avoid the use of glue and tomake each panel or tile very zo strong and. compact for itself by theexterior band. and the laterall connection of the individual woodenpieces or blocks forming each panel. v

Having thus described ni'y invention, I claim 15 as new and desire tosecure by Letters Patent-M ROBERT NILII ELTZNER.
